ALFBED HANNAFORD, OFCHICAGO, ILLINOIS, ASSIGNOR TO ALLBRIGHT-NELL COMPANY, A CORPORATION OF ILLl NOIS.

.. BEATER-ARMS FOR ANIMAL CLEANING ol't DEflAlRlNG MACHINES.

To. all whom'it may concern:

BEG-1t known that I, ALFRED I-Lmnarono, a c1tizen-of the-United States,residing at Chicago, in the-countyof Cook and State of Illin01s, haveinvented certain new and use fullImprovements in Beat'e1'- \1'n1s forAnimal- Cleaning or Dehairing Machines, of which. the following is aspecification.

Beatersor beater arms for hog scraping machines heretofore have beenconstructed of a piece offl'cxible material, such as canvas, one end ofwhich is attached to the shaftand theopposite end projects outwardlyfrom the shaft-and blades are secured on saidlout'er end; Such beaterarms do not act satisfactorily owing to the fact that the con tinualbendingwof the arms caused by the impact on the carcasses causes saidarms or heaters to permanently set in a curve thereby destroying theirflexibility and consequently their utility.

' It is an object of this invention to provide a flexible beater adaptedto act by impact on the carcasses to beat the hair, scurf, etc.therefrom and which will not set in a permanent curve but which retainsits elasticity for the entire life of the beater.

It is further an object ofthis invention to provide a'beater in whichboth ends thereof are secured to the shaft and on the same side thereofproviding two diverging arms connected by an integral lopp, one arm ofwhich acts to brace the other and in which one arm and the loo preventsbu'cklingof the beater.

It is furt er an object of this invention to rovide means for preventingthe heaters ending short atthe point of attachment to prevent theheaters cracking or breaking at oint. It is further an object of thisinvention to provide a very simple beater cheap to con-, struct andwhichis highly efficient. Figure 1 is an end elevation of devices Fig. 2 is aside elevation thereof. v

As shown in the drawings: 10, indicates a beater shaft mounted to rotatein any suitable manner and'driven by any suitable 'n'aeans, which,inasmuch as it forms no part of this invention, is not shown.

--The beaters indicated as a whole by 11, are

- each constructed of .a single flexible strip of canvas or othersuitable material which is Specification of Letters Patent. Applicationfiletl June 12,1908; Serial No. 433,151.

folded together for its ends 1213 to meet on one side of the shaft. Fromsaid superposed ends 12--13 the webs of the beater diverge outwardlyforming twochvergmg Patented Apr. 12,191()., I

arms which are integrally connected at their outer ends by a loop Saidheaters are secured to the shaft by means of bolts 14, which passthrough both ends of the beater strip and through the shaft. Secured onthe forward side of each healer are a plurality of blades 16, l'onwhipiiing or-beating the hair and scurf .l'rom the carcasses,vwhicli aresecured thereto by means of rivets 17. or in any-other preferred manner.

As shown, each blade is curved forwardly and the outer extremity 18,thereof lies in a plane in advance of the beater arm; To prevent thebeater arms short bending. at the point of attachment with the shaft,rearwardly curved guard plates 19, are provided, one secured on therearsideof each heater and around which the beater bends wherv the samestrikes the carcasses.

The operation is as follows: As the shaft 10, constantly rotates theheaters strike the carcasses and the blades secured thereon whip andbeat the bristles, scurf, nails, etc. from the carcasses, cleaning andpolishing the same. The diverging arms of each beater connected by theloop form a resilient, yet comparatively stiff, beater. As each beaterstrikes the carcass, owing to the force of the impact the heater issomewhat flattened (as shown in dotted lines in Fig. 1.) forcing thedivergent arms closer together, slightly elongating the heater anddecreasing the curvature of theloop. The beater arms are also bent attheir inner ends around the curved guide 19, which increases the tensionthereof adapting the beater when released to spring to normal positionand the pressure at the outer end of the loop being released, said loopassumes its normal curvature forcing said arms to their normal degree ofdivergency. When bent around the guide 19, the arm of the beater is bentshorter than the forward arm. This increases the life of the forward armand said rear arm acts as a powerful brace which is under greatertension than the forward arm ting in a curve and consequently theheaters retain their elasticity for the entire life of the material ofwhich constructed.

The arms may be arranged oppositely or sta gered or in any desirab emanner and in eac instance the loops are directed transversely of theshaft. I

Details of theconstrnction may be varied and I do not desire to limitthis application for patent otherwise than necessitated by the priorart.

I claim as my invention.

1. A beater formed of a strip of flexible and resilient material bent toform a 100 at the outer portion and secured at the en s which aresuperposed.

2. A beater consisting of a strip bent to form oppositely inclined armsand a loop and metallic blades secured to one of the inclined arms.

3. In a device of the class described a shaft, a beater secured theretoformed with' and resilient material bent to form a 100 at the outerportion and secured at the en 3 and metallic blades secured to thebeater.

6. In a device of the class described a shaft, a beater formed of astrip of flexible and resilient material bent to form a loop at theouter portion and the ends secured to the shaft, metallic blades securedto the heater and curved forwardly, and a curved guard late secured tothe shaft on the outer side 0 the ends. 7 A flexible and resilientbeater constructed of a stri of. material bent to form a loop metallic bades secured to the beater curved forwardly and plates secured againstthe beater curved rearwardly to prevent short bending. of the heater.

,8. In a device of the class described a shaft, a beater secured theretoconstructed of belting formed with a loop at the outer end thereof andhaving the greatest width of the belting directed longitudinally of theshaft.

In testimony whereof I have signed my name to this specification, in thepresence of two subscribing witnesses, on this 10th day of June A. D.1908.

ALFRED HANNAFORD.
